Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The group of vertebrae located dorsal to the thoracic region; noted for their tall dorsal spinous processes.






2. The joint between the pelvis and the sacrum that joins the pelvic limb to the axial skeleton.






3. Large - multinuclear cells of bone that absorb bone and structures and reshape or remodel damaged bones.






4. The microscopic - laminated cylinders of bone that make up compact bone. Oriented lengthwise in a long bone - these consist of a central haversian canal surrounded by concentric layers of bone. Osteocytes in their lacunae are present at the junctions






5. The most caudal of the three pairs of bones that make up the pelvis.






6. The skull bones that do not surround the brain. External bones: the incisive bones - the nasal bones - the lacrimal bones - the maxillary bones - the zygomatic bones - and the mandible. Internal bones: the palatine bones - the pterygoid bones - the v






7. The hormone secreted by the thyroid gland that prevents the level of caclium in the blood from getting too high.






8. Bony arches below and behind the eyes of common domestic animals; in dogs and cats they form the widest part of the skull. Made up of the rostral - facing zygomatic process of the temporal bone joined with the caudal - facing temporal process of the






9. The most proximal bony structure of the pelvic limb; also known as the os coxae. Attaches to the sacrum dorsally at the sacroiliac joints and forms the hip joints with the heads of the femurs.






10. The fluid - filled potential space between the joint surfaces of a synovial joint; normally filled by synovial fluid.






11. The concave articular surface of the scapula; the socket portion of the ball - and - socket shoulder joint.






12. A joint that allows only a rotary motion; the only true joint of this type is the atlantoaxial joint ('no joint').






13. Skull bones that are the bones of the ear; three pair of bones in the middle ear that transmit sound wave vibrations from the tympanic membrane to the inner ear.






14. The large hole in the occipital bone through which the spinal cord exits the skull.






15. The immovable fibrous joints that unite most of the skull bones; also known as synarthroses.






16. The long - flexible - caudal portion of the dorsal body cavity formed by the adjacent arches of the vertebrae of the spine; it houses and protects the spinal cord.






17. The 'forearm' region of the thoracic limb.






18. Skull bones that are part of the external bones of the cranium; located on the dorsal midline just rostral to the occipital bone.






19. Blood cell production; usually occurs in red bone marrow.






20. The solid structure formed by the fusion of the sacral vertebrae.






21. One of the irregular bones of the spinal column.






22. The paranasal sinus in the sphenoid bone; only present in horses.






23. The main growth area of a bone developing by endochondral method; areas of bone development that are located in the main portions of the cartilage rod bone templates in the developing fetus.






24. Long - faced. Example: Collie.






25. A longitudinal ridge on the front of the proximal end of the tibia.






26. Short - faced; breeds including Boston terriers - pugs - English bulldogs - and Pekingese.






27. One of countless tiny channels through the matrix of bone that bring blood in from the periosteum to the haversian canals in the centers of the haversian systems. The haversian systems run lengthwise in long bones while these canals come in at right


28. Paired sesamoid bones in the legs of horses; located in the large digital flexor tendons behind the fetlock joints.






29. The visceral bone in the snout of swine that strengthens it for the rooting behavior of pigs.






30. Secondary areas of growth in bones developing by the endochondral method; areas of bone development located outside the main portions of the carilaginous bone templates in a developing fetus.






31. The last - most caudal sternebra; the _____ process.






32. A band of fibrous connective tissue that is present in and around many synovial joints; connect the bones of the joint to each other.






33. A joint movement that consists of a twisting motion of a part on its own axis.






34. Viscous fluid formed by the lining layer of the joint capsule of a synovial joint; lubricates joint surfaces.






35. The joint between the femur and the tibia; called the knee joint in humans.






36. The bones of the skull that surround the brain. External bones: the occipital bone - the interparietal bones - the parietal bones - the temporal bones - and the frontal bones. Internal bones: the sphenoid bone and the ethmoid bone.






37. Incoordination; animals with this make jerky - spastic movements.






38. The healing tissue between the ends of a fractured bone that is eventually replaced by true bone as the fracture heals.






39. Skull bones that are part of the external bones of the face; form the bridge of the nose or the dorsal part of the nasal cavity.






40. A joint whereby one surface swivels around another like a door hinge; also called a ginglymus joint. The only movements possible are flexion and extension; the elbow is an example.






41. The hormone secreted by the parathyroid gland that prevents the level of calcium in the blood from getting too low.






42. The visceral bone in the heart of cattle that helps support the valves of the heart.






43. The growth plate of a long bone; located at the junction of the proximal and distal epiphyses with the diaphysis. They are areas where long bones increase in length by the process of endochondral bone formation. When an animal reaches its full adult






44. The joint movement whereby an extremity is moved toward the median plane.






45. The cartilaginous ventral portion of a rib.






46. The second cervical vertebra; it forms the atlantoaxial joint with the first cervical vertebra - the atlas.






47. Skull bones; external bones of the face. These two bones make up most of the upper jaw and house the upper canine teeth - if present - and all of the cheek teeth.






48. A toe that does not reach the ground - such as the first digit of dogs and cats and the rudimentary medial and lateral toes of cattle.






49. The long bone of the brachium or upper arm.






50. A space within a skull bone that is an outpouching of a nasal cavity; depending on the species - these are found within the frontal bones - maxillary bones - sphenoid bones - and ethmoid bones.
